Abstract: This paper divides independent innovation into the independent innovation of intermediate products and that of final products, and demonstrates the theoretical logic of and feasible approach for leading and creating new demands through independent innovation. It is found that due to uncertainties inherent in the innovation process and the switching cost effect, the independent innovation of final products can only create the consumption demand, but cannot drive the investment demand for upstream intermediate products. However, the independent innovation of intermediate products has positive externalities, which can not only create the investment demand for intermediate products per se, but can also lead and create new demands in the whole industrial chain. Therefore, encouraging the independent innovation of intermediate products is the key to expanding the domestic demand. As a starting point for leading and creating new demands, the independent innovation of final products can be achieved to some extent through the market, in the form of mass entrepreneurship and innovation. In contrast, the success of the independent innovation of intermediate products requires intensive government intervention and support, especially the role of stateowned enterprises. On this basis, this paper presents some policy suggestions on how to lead and create new demands through independent innovation.
